Problems solved by technology

[0002] Among all kinds of renewable resources, wind energy is the most competitive. In the long run, the prospect of the global wind energy industry is quite optimistic. Governments of various countries have continuously issued incentive policies conducive to the development of renewable resources. At present, the development of global wind power is entering a period of rapid expansion. This is undoubtedly a positive signal for the wire and cable industry. However, our research on wind energy cables has just started. In addition, due to the harsh environment of wind power generation and the long service life of wind turbines, the aging resistance of existing wind power cables And the twist resistance is not very good, often can not meet the requirements of the use of wind power cables, thus limiting the application of wind power cables

Abstract

The invention discloses an anti-aging and anti-twisting wind power cable. The anti-aging and anti-twisting wind power cable comprises a copper conductor, wherein an insulation layer is coated at the exterior of the copper conductor, a winding layer is coated at the exterior of the insulation layer, and a protective sheath layer is coated at the exterior of the winding layer; the protective sheath layer is made of polyurethane composite material; the polyurethane composite material is prepared form the following raw materials in parts by weight: 50 to 80 parts of polyurethane, 20 to 35 parts of nylon, 10 to 20 parts of ABS (acrylonitrile-butadiene-styrene) resin, 3 to 12 parts of diphenyl-methane-diisocyanate, 2 to 10 parts of montmorillonoid, 3 to 12 parts of kaolin, 2 to 10 parts of talcum powder, 3 to 12 parts of zinc borate, 3 to 15 parts of aluminium hydroxide, 10 to 25 parts of carbon fiber, 2 to 4 parts of silane coupling agent, 0.5 to 2 parts of antioxidant, 5 to 15 parts of phosphorus-containing flame retardant, and 0.2 to 1.5 parts of lubricant; the phosphorus-containing flame retardant is formed by reacting para aminobenzoic acid and tetrakis hydroxymethyl phosphonium sulfate. The anti-aging and anti-twisting wind power cable has the advantage that the anti-aging, anti-twisting and flame-retardant properties are excellent.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an aging-resistant and twist-resistant wind power cable. Background technique [0002] Among all kinds of renewable resources, wind energy is the most competitive. In the long run, the prospect of the global wind energy industry is quite optimistic. Governments of various countries continue to introduce incentive policies that are conducive to the development of renewable resources. At present, the development of global wind power is entering a period of rapid expansion. This is undoubtedly a positive signal for the wire and cable industry. However, our research on wind power cables has just started. In addition, due to the relatively harsh environment of wind power generation and the long service life of wind turbines, the existing wind power cables have aging resistance. And the twist resistance is not very good, often can not meet the requirements of the use of wind power cable...
